What is Reqg virus?
Reqg virus is a new ransomware that belongs to the family of ransomware called STOP (Djvu). Ransomware is a form of malware that encrypts the victim’s files and demands a ransom for decrypting them. The Reqg virus encrypts files, renames them by appending the .reqg extension, and creates files named “_readme.txt” containing the ransom demand message. For example, a file named “image.jpg” will be renamed to “image.jpg.reqg”, a “document.docx” file to “document.docx.reqg”, “invoice.pdf” to “invoice.pdf.reqg”, and so on.

Reqg ransomware is new malware that is the 324th variant of STOP (DJVU) ransomware. Like other variants of this ransomware, it is distributed through key generators, cracked software, adware and torrents web-sites. Upon execution, Reqg creates a folder in the Windows system directory and copies itself there. Then the virus changes some Windows OS settings so that it starts automatically every time the PC is turned on or restarted.
Reqg ransomware collects information about the victim’s computer, after which it tries to establish a connection with its command-and-control server (C&C). If the connection has been established, the virus receives a key (so called ‘online key’) that will be used to encrypt files. In addition, Reqg virus may receive additional commands and files that will be executed on the victim’s computer. If Reqg ransomware could not connect to the command server, then it uses a fixed key, which the security researchers called ‘offline key’.
There is a significant difference between ‘online key’ and ‘offline key’. The online key is unique for each victim, that is, the key from one victim will not help decrypt the files of the other victim. The offline key is the same for all victims. Thus, it can be used to decrypt files regardless of where they were encrypted.
Having a key to encrypt files, Reqg virus proceeds directly to the process of encrypting files. It encrypts file-by-file, so that all files of the victim will be encrypted. It doesn’t matter where the files are located, on the internal drive, flash drive, external media, cloud storage, all of them can be encrypted. There is a small exception, the virus does not encrypt files located in the Windows system directories, files with the extension from the list ‘.lnk, .bat, ini, .sys, .dll’ and files with the name ‘_readme.txt’. Thus, almost all of the victim’s data will be encrypted, including documents, pictures, databases, archives and other types of files, such as:
.2bp, .z, .snx, .vcf, .zabw, .bay, .iwi, .dxg, .rwl, .jpeg, .wpg, .mpqge, .bkf, .m2, .accdb, .zw, .3dm, .tor, .xar, .xy3, .p7c, .svg, .icxs, .wsc, .1, .ai, .xdb, .wbc, .xf, .xlgc, .erf, .ptx, .bik, .wsd, .qdf, .dcr, .crw, .wbd, .jpg, .wot, .kf, .esm, .psd, .txt, .y, .webdoc, .sav, .m4a, .zi, .ibank, .qic, .wgz, .xyp, .pem, .dbf, .fpk, .xxx, .py, .bsa, .wp7, .ztmp, .itdb, .xlsx, .ff, .mddata, .x3d, .pak, .arw, .litemod, .xls, .xml, .fos, .bc7, .cdr, .desc, .wp4, .kdb, .wma, .lvl, .mef, .xpm, .sb, .forge, .itl, .sidn, .hvpl, .xls, .mov, .mlx, .dazip, .tax, .jpe, .csv, .zdc, .odp, .wp6, .wmo, .raf, .sql, .raw, .t13, .wpa, .pfx, .7z, .xlk, .ppt, .wpb, .hkx, .p7b, .odc, .xlsb, .wpd, .big, .nrw, .odm, .sie, .ysp, .sidd, .cas, .wpe, .avi, .wav, .wbk, .wmv, .wire, .gho, .pkpass, .slm, .zif, .ltx, .wn, .indd, .odb, .wmf, .vpk, .dmp, .wm, .itm, .0, .xll, .rb, .mdf, .xlsm, .mrwref, .wcf, .cer, .re4, .wbmp, .syncdb, .dba, .x3f, .xmind, .vfs0, .wotreplay, .fsh, .ncf, .cfr, .wbz, .xwp, .wsh, .rar, .yml, .r3d, .dng, .db0, .arch00, .wmd, .bc6, .orf, .flv, .1st, .xx, .apk, .rtf, .pst, .vtf, .rgss3a, .doc, .rw2, .ntl, .vpp_pc, .wri, .lrf, .wpw, .gdb, .wpt, .xyw, .js, wallet, .ods, .rim, .der, .t12, .zdb, .vdf, .psk, .epk, .bkp, .ybk, .pptx, .3fr, .upk, .menu, .odt, .mp4, .wmv, .wp5, .sid, .docm, .hkdb, .iwd, .cr2, .xbdoc, .pptm, .xlsm, .xld, .crt, .wbm, .d3dbsp, .asset, .sum, .kdc, .wb2, .ws, .mdbackup, .css, .eps, .map, .w3x, .wpl, .zip, .png, .wp, .docx
The Reqg virus renames encrypted files. It will append the ‘.reqg’ extension to the name of each encrypted file. To encrypt as many files as possible in the minimum time, the virus does not encrypt the entire file, but only its initial part in the amount of 154 kb. Reqg virus encrypts files sequentially, when all files in the directory are encrypted, it places a new file in it. This file is called ‘_readme.txt’ and its contents are shown below.
Screenshot of the contents of ‘_readme.txt’ file (ransom note)
This file is a ransom note that is a message from Reqg creators. In this message, the criminals say that the victim’s files are encrypted and there is only one way to decrypt them – purchase the key and the decryptor from them. Attackers set the price for the key and decryptor at $980. If the victim pays the ransom within 72 hours, then Reqg authors agree to make a discount of half the ransom, that is, reduce the size of the ransom to $490. Criminals offer to decrypt one file for free. To do this, the victim needs to send this file to one of the email addresses listed in the ransom demand message. But successful decryption of one file does not guarantee the possibility of decryption of files even after payment of the ransom.

| Decryption | Reqg File Decrypt Tool |
In the ransom note, the Reqg authors say that it is impossible to decrypt files without a key and a decryptor. In general, this is true; to decrypt .reqg files, you must use the key and the decryptor. This is confirmed by the security researchers. Fortunately, there is a free Reqg File Decrypt Tool, which in some cases can decrypt .reqg files. In the case when it could not decrypt encrypted files, there are several more methods, each of which can help you restore the files encrypted by Reqg virus. These methods do not require the use of a key and decryptor, and therefore are suitable in all cases.
How to remove Reqg virus (ransomware)
Before you start decrypting or recovering .reqg files, you need to remove the Reqg autostart entries. This must be done since otherwise the ransomware may re-encrypt the restored files. You can stop the ransomware from working, as it is not difficult to do. Another option is to perform a full system scan using free malware removal tools capable of detecting and removing ransomware infection. Read the entire manual carefully. To make it easier for you to follow the instructions, we recommend that you print it or open it on your smartphone.
It is very important to scan the computer for malware, as security researchers found that spyware could be installed on the infected computer along with the Reqg ransomware. Spyware is a very dangerous security threat as it is designed to steal the user’s personal information such as passwords, logins, contact details, etc. If you have any difficulty removing the Reqg virus, then let us know in the comments, we will try to help you.
To remove Reqg virus, follow the steps below:
Kill Reqg virus
Press CTRL, ALT, DEL keys together.
Click Task Manager. Select the “Processes” tab, look for something suspicious that is the Reqg ransomware then right-click it and select “End Task” or “End Process” option. If your Task Manager does not open or the Windows reports “Task manager has been disabled by your administrator”, then follow the guide: How to Fix Task manager has been disabled by your administrator.
It is not difficult to detect a process related to the Reqg ransomware. When looking for a malicious process, pay attention to the process icon and its name. Most often, this ransomware has a process name in the following format: 4-characters.tmp.exe or 4-characters.exe. For example: 7533.tmp.exe, A4b1.exe, CD15.tmp.exe, 19b2.exe. The process name can also contain “(32 bit)”. If you do not find a process with a similar name in the list of processes, then most likely the Reqg ransomware has finished working. But keep in mind, if you do not remove the ransomware autostart entries, as demonstrated below, and do not delete its file, then after a while it may start again, and if it finds unencrypted files, immediately encrypt them.
Disable Reqg Start-Up
Select the “Start-Up” tab, look for something similar to the one shown in the example below, right click to it and select Disable.
Close Task Manager.

How to decrypt .reqg files
To decrypt .reqg files, you need to use a unique key and decryptor. Security researchers confirm that it is impossible to access the contents of encrypted files without decryption. Renaming files and changing their extension will not help, the files will remain encrypted. Fortunately, there is a free Reqg File Decrypt Tool called STOP Djvu decryptor. In some cases, it can help decrypt .reqg files.
Free Reqg File Decrypt Tool (STOP Djvu decryptor)
To decrypt .reqg files, use Reqg File Decrypt Tool
- Download Reqg File Decrypt Tool from the following link.
STOP Djvu decryptor - Scroll down to ‘New Djvu ransomware’ section.
- Click the download link and save the decrypt_STOPDjvu.exe file to your desktop.
- Run decrypt_STOPDjvu.exe, read the license terms and instructions.
- On the ‘Decryptor’ tab, using the ‘Add a folder’ button, add the directory or disk where the encrypted files are located.
- Click the ‘Decrypt’ button.
Reqg File Decrypt Tool is a free software that can decrypt files only in some cases, when the files were encrypted with an ‘offline key’. If the files were encrypted with an ‘online key’, then they cannot be decrypted. The reason for this is that the decryption key is in the hands of criminals and this key can not be determined. But even in this case, there is a chance to restore the contents of encrypted files, we will talk about this in section “How to restore .reqg files” of this article.
How to find out which key was used to encrypt files
Since Reqg Decrypt Tool only decrypts files encrypted with the offline key, each Reqg’s victim needs to find out which key was used to encrypt the files. Determining the type of key used is not difficult. Below we give two ways. Use any of them.
Personal ID is highlighted here
Find out the type of key using ‘_readme.txt’ file
- Open the ransom demand message (‘_readme.txt’ file).
- Scroll down to the end of the file.
- There you will see a line with the text ‘Your personal ID’.
- Below is a line of characters that starts with ‘0324’ – this is your personal id.
Find out the type of key using ‘PersonalID.txt’ file
- Open disk C.
- Open directory ‘SystemID’.
- Open file named ‘PersonalID.txt’. This file lists ‘Personal ID’s that match the keys that the virus used to encrypt files.
The ‘Personal ID’ is not a key, it is an identifier related to a key that was used to encrypt files. If the ID ends with ‘t1’, then the files are encrypted with an offline key. If the ID does not end with ‘t1’, Reqg virus used an online key. If you could not figure out how to determine which key was used to encrypt files, then we can help. Just write a request here or in the comments below.
Reqg File Decrypt Tool : “No key for New Variant online ID”
If, when you try to decrypt .reqg files, Reqg File Decrypt Tool reports:
No key for New Variant online ID: *
Notice: this ID appears to be an online ID, decryption is impossible
It means that your files are encrypted with an ‘online key’ and their decryption is impossible, since only the Reqg authors have the key necessary for decryption. In this case, you need to use alternative methods listed below to restore the contents of encrypted files.
Reqg File Decrypt Tool : “No key for New Variant offline ID”
If, during decryption of .reqg files, Reqg File Decrypt Tool reports:
No key for New Variant offline ID: *t1
Notice: this ID appears be an offline ID, decryption MAY be possible in the future.
It means the following: your files are encrypted with an ‘offline key’, but the key itself has not yet been obtained by security researchers, in this case, you need to be patient and wait a while, in addition, you can also use alternative ways for recovering encrypted data.
If for some reason you were unable to decrypt the encrypted files, then We recommend to follow the news on our Facebook or YouTube channels. So you ‘ll know right away that it ‘s possible to decrypt .reqg files.
This video step-by-step guide will demonstrate How to remove Reqg virus, Decrypt/Recover .reqg files.
How to restore .reqg files
If Reqg File Decrypt Tool did not help you, or your files are encrypted using an online key, then there is no need to panic! There are several other alternative methods that may allow you to restore the contents of encrypted files. Once again, remember to be sure to scan your computer for ransomware and malware using free malware removal tools. You must be sure that Reqg ransomware is completely removed.
